x = 17/5
Step-by-step explanation:
Plug in 2y + 3 as x in the second equation and solve for y to get 1/5
Then plug in y into the first equation and solve for x to get 17/5

Step-by-step explanation:
x=2y+3
3x=7-4y
Rearrange the numbers so they compare,
x=2y+3
3x=-4y+7
Multiply the first equation by 2 (this is so the variable with y matches in both equations)
2x=4y+6
3x=-4y+7
Add the two equations together
2x=4y+6
+
3x=-4y+7
5x=13
Divide both sides by 5 to isolate x
x=13/5
Simply the equation
x=2 3/5
